Given that the diameter of a hemispherical tank d = 14m.
Then the radius of the hemispherical tank r = d/2 = 14/2 = 7m
We know that Capacity of the tank = 2/3pir^3
= 2/3 * 22/7 * (7)^3
= 2/3 * 22 * 7 * 7
= 718.67 m^3
= 718.67 kilolitres.
Given that the tank already contains 250 kilolitres of water.
Therefore the volume of water pumped into tank = 718.67 - 250
= 468.67 kilolitres.
Hope this helps!
